Can We Hear Bat Cries? Investigating the Frequency Range of Bat Sounds

  • Thread starter Thread starter knockout_artist
  • Start date Start date
AI Thread Summary
Bats produce sounds primarily in the ultrasonic range, typically above human hearing capabilities. The user was able to hear bat cries from a downloaded wave file, raising questions about the sound's manipulation. It's suggested that the sound may have been altered, possibly through techniques like frequency modulation or downsampling, to bring it within audible range. Analyzing the file with a Fast Fourier Transform (FFT) could reveal frequencies beyond human hearing. Understanding these modifications can clarify how bat sounds can be perceived by humans.

Homework Statement


I downloaded wave files of bat cry. I played it on computer And I was able to hear it?
Shouldn't that be ultrasonic??

Here is the sample

How do you think you are able to hear it? What could they have done to the sound to make you able to hear it?
 
Did some tempered it? re-modulate it on lower frequency so we could hear it?
 
Bats use a whole range of frequencies.
 
oh
you mean if use fft on the sound file I will see frequency above haring range??
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
